CRUSHER FOR SEED-EXTRACTING MACHINES.

To all whom t may concern Y Be it known that I, Bunn N. TRAUTMAM a citizen of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented a newvand useful Crusher for Seed-Extracting Machines, of which the following is a'speciiica tion.

This invention relates to crushers; par ticularly to 'ci-ushers adapted for seed ex tiacting machines.

The object of the invention is toprovide a construction which will thoroughly crush all kinds of fruits seeds.

seed extracting machine and is to be used in connection with a vibrating riddle of the type disclosed in my Patent No. 1,266(i11,A

dated May 21,1918, or of any similar type. The claims insaid'patent werelimited to the riddle. The present crusher represents an improvement on the Crusher disclosed by said patent. For an improved type of riddle, reference should be made to an applica tion filed of even date'herewith, SerialNo.

The invention will be best understood from a consideration of the following de tailed description taken in connectionwi'th the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing in the drawings, but may be changed and modii lied so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appendedclaims.

In the drawings,

Figure 1 is a cross crushing rolls and hopper of a Crusher constructed in accordance with the present in vention.

Fig. 2 is a top plan view showing the hop' i per removed.

Fig. 3 is a cross section at right angles to the section of F-ig. 1.

Fig. 4 is a detail perspective view of the crusher comb] Y y p v Fig. 5 is asimilar view of the tooth-cleanj ing means.

The numeral 10 denotesa hopp-er' member y which may vbe of Vany preferred... form, the drawings showing a shallow rectangular and vegetables having i l 21 isV fixed to shaft19. The same driving The present invention forms apart of a the periphery of lthe roll 17.

riddle below (not shown).

Crushing rolls 16 and 17, ymounted upon shafts 18 and 19, are arranged within the crushing chamber referred to. A pulley 20 is secured tothe shaft-18 and a'larger pulley means will be connected to both pulleys, re` sulting in an unequal'angular'velocity im-` parted to the crushing rolls. The horizontal axes of the two rolls are each `disposed directly below one of the edgesk defining `the opening 11, this disposition being* clearly illustrated in Fig. 1.

Specification of Letters Patent. A Patented luay V17 192L Application filed Ap11f12, 1920.v Serial No.` 373,332. Y

- Each roll is piovidedwith a series of re- 'i movable teeth 22. These teeth are "preferably cylindrical pins having heads 23 adapted to be engaged by a wrench and hav#l ingscrew threaded portions engaged with Y tappedzvbores at :desired points in the rolls.v

The'rolls are hollow as indicated and the various teethvmay be removedby working from either end of said roll. This removability is desirable whenciushing large melons, as watermelons, l Y

-A cruslier comb is provided immediatelyv below the hopper opening 11 to cooperate with the teeth of the rolls to aid in crushing thefruit or vegetables. This comb coinprises a framework including uprights 24 secured by ele-ments 25 to thesides 14 of i the crushing chamber and a horizontal niem-r section through the bershaped like an inverted V carrying the series ofy spaced downwardly inclined flat bars 27. 4

A tooth-cleaningelement is mounted bef tween the rolls directly below the Crusher comb ijust described,- this cleaning element comprising end walls v28 secured by means 29 to the` sides of the crushing compartment and a curved face 31. v The curvature l ofthe face 31 is such that its arc is concentric with, though of kgreater radius than, The spacing of `the curvedfaeel from the roll 17 is,` such that the lteeth of said roll do vnot quite touch said ,curved face as the roll is revolved.

Teeth 32 precisely the same as the teeth 22 of the rolls are provided short of the lower end of the concaved face 31, the teeth 32 being arranged in one or more rows extending lengthwise of the cleaning element. The teeth 32 are removable so that when watermelons or the like are crushed there will be no interference with the feed down to the riddle below. The teeth 32 are so set that they will not interfere with the arcuate movement of any of the teeth 22 but will clean the roll teeth as they move downwardly. rihis will be seen from Fig. 1 `of the accompanying.drawings. The upper portion of the cleaner element is provided with a series of spaced slots 30 corresponding in number to the number of teeth on the roll 16, such slots beingcleaning slots for cooperating with the teeth oit' said roll in the same manner as do the teeth 32. Vhese slots are provided on the concaved face 31 and are of suiiicient length to pass the rotating teeth ot roll 16 without'interference, though operating to clear said teeth oi' any vegetable matter adhering thereto. rlhe upper edge of the'cleaner element is located very close to the periphery of roll 16 so that the roll, as well as the base of the teeth which it carries, will be kept clean.

The Crusher comb shown apart from the Crusher in Fig. il is removable so that many different varieties and sizes oi' fruits and vegetables may be crushed to eii'ect extraction of their seeds. For certain large melons probably the comb shouldrbe removed, but for smaller fruits and vegetables the comb has been found to be very eiiicacious in breaking up the pulp and is considered to be an important part of my invention.

The rolls are rotated in opposite directions so as to draw the fruits or vegetables between them, and the .different speeds at which the rolls are revolved insure a periect crushing of the material as well as a quick and certain feed ot' the same. The disposition of the parts of the hopper relative to the crushing rolls is such that none of the material will be thrown out by the rolls, but all parts or" the crushed vfruits or vegetables will be dropped upon the vibratory riddle below where the actual seed eX- traction takes place. The cleaning element acts to remove all the materialV from the teeth of the rolls as fast as the crushing has taken place; thus the rolls do not carry the material around with them in their revolution and therefore do not become clogged however iast the feed of the vegetables or fruits may be. The curved 4face 31 acts to guide the crushed material down to the vi brating riddle below and delivers the material on the proper part of theriddle. The material falls in a stream beneath roll 17 deflect crushed material from one of the rolls and deliver the same in a stream beneath the other roll.
